Strength of the bonds.
The basic principle of the bond is that the adhesive interacts with the adherents' surfaces and holds them together to act as one. In order to function as a bond, the adhesive should intermittently flex when the surfaces flex-stretch.
When these two surfaces or parts are different in nature, their thermal behaviors and CTE's (Coefficient of thermal expansion) will be different therefore adhesive system applied should be able to tolerate these differences.
On the other hand, the flexible resin-based adhesives have lower mechanical strength when flexed and their adhesion forces decline with temperature increases.
The Politix series Fleksotix, Fibrotix, VEtix and FibroVEtix offers optimum balance in flexibility, strength and durability. This high performance combination is a result of special modified- hybrid structure of polyester polymer and vinyl ester base.
Another important factor is the selection of the bonding paste according to design specifications. Because bonds will be subjected to various types of forces. These forces should be taken into consideration for safety and reliability reasons the bonded joint should be capable to handle these force loadings.
Sample forces effecting bonds
Politix Tix
Repair type — Bonding paste
 
Tix is a hard forming paste; it is for filling surface gaps on inflexible, thick, rigid composites parts or marble-granite applications. Also Tix is used to modify the thixotropy of the standard resins. It is not suitable for combining flexible GRP parts together.
Politix Fleksotix
Flexible and strong type — Bonding paste
Fleksotix is a flexible polyester resin-based bonding paste for GRP parts which contains no fibers or fillers.
It is specially designed to combine foam-sandwich parts in the marine industry.
Normally, standard high exotherm and high shrink polyester based adhesives, when used on thin laminates in regions where a sandwich structure bonds the foam there can be fluctuations and undulation on the surface.
Also, they have a tendency to show the shadow of the other part on the outer surface. Due to the special curing system, Fleksotix does not generate high exotherm which helps to prevent surface distortion.
Politix VEtix
Repair type — Vinyl ester bonding paste
VEtix is a bonding paste for high-strength structural composite products. VEtix has very high fatigue resistance because of its vinyl ester resin structure.
It is designed as an adhesive for GRP parts specifically designed to combine foam-sandwich parts in the marine industry. Its hardness is in between Fleksotix and Tix.
Politix Fibrotix
Repair type — Fiber reinforced flexible and durable - Bonding paste
Fibrotix contains fillers which tend to balance the volumetric shrinkage of the matrix resin, and also contain glass fibers which increase the adhesion strength. Fibrotix share the same flexible, strong and durable hybrid base polymers used in Fleksotix and designed for thermal resistance requiring applications while Fibrotix is designed where flexibility is more important.
It is suitable for the spatula application and can be applied up to 10-15mm thickness without dripping. It should be applied with a spatula in layer of films in order to avoid leaving air trapped between the adherent surfaces and bonding paste. If a thicker application is required, a two-layered mass is a better option to minimize the air bubbles in the bond. Fiber reinforced and filled bonding pastes are also used in bonding GRP composites parts to fill the gaps where lamination is difficult due to jagged surfaces.
Politix FibroVEtix
Fiber reinforced Vinyl ester based — Bonding paste
FibroVEtix contains fillers which tend to balance the volumetric shrinkage of the matrix resin, and also contain glass fibers which increase the adhesion strength. FibroVEtix share the same flexible, strong and durable hybrid base polymers used in VEtix.FibroVEtix is designed for reinforced uses.

Features of the Politix adhesive series
Poliya offers new alternative bonding pastes for both GRP and filled composite applications. This new bonding paste system is based on high-tech polyester and vinyl ester structures. You can select the most suitable adhesive system depending on your applications. Types include all resin based or glass-fiber and filler modified adhesive systems.
Flexible, Strong and Durable
The Politix series Fleksotix, Fibrotix, VEtix and FibroVEtix offers optimum balance in flexibility, strength and durability. Classical polyester-based adhesives are usually very hard and inflexible. After the joined- composite parts are subjected to vibration and shock in everyday use, eventually they seperate or the bond is broken.
On the other hand, the flexible resin-based adhesives have lower mechanical strength when flexed and their adhesion forces decline with temperature increases.
Water — Chemical resistance
Politix adhesive systems are water and chemical resistant thanks to their Isophtalic—NPG based and modified structure. For even higher performance and resistance, VE (vinyl ester modified) versions are available.
Politix VEtix and FibroVEtix’s water and chemical resistance is superior because of their vinylester base and advance modifications. Politix adhesive systems, with their outstanding permanent bonding features, offer water and air tightness.
Different practices and alternatives
Politix Bonding Paste series offers different types of bonding for numerous applications. Tix is designed to fill the gaps on the surfaces. Fleksotix and VEtix are designed to join the foams in sandwich structures. Fibrotix and FibroVEtix offers the highest durability and strength.
Low exotherm and low shrinkage
Politix products are specifically designed to prevent deformation during hardening.
The Politix series including Fleksotix, VEtix and Fibrotix generate low exothermal shrinkage during cure thanks to their special polymeric structure.
An economical alternative
In some cases, Politix products are economical alternative to acrylic, epoxy and polyurethane-based adhesives. Manufacturers can evaluate and adapt Politix in Metal insert and brackets bonding.
Important Points in Composite Bonding and Joints
Conventional mechanical joining methods (Rivet, Welding, Bolt etc.) have very high performance in holding load and tensile resistance. On the other hand, Politix™ Bonding Pastes also have their advantages. They can distribute stress on large surfaces and the adhesion surfaces' geometry and size can be customized and lightweight.
Prior to bonding process, the surface should be dirt, dust and oil free. The adhesion strength does not depend merely on bonding pastes' performance but bond's geometrical shape is also very important. You should avoid tensile stress on the adhesive and also pressure or shear stress on bond's plane should be considered. For example;
Not recommended!
Bonded joint exposed to the tension force – Weak bonding.
Medium performance
Prior test should be made before the application
As seen to the left, shear force accompanies tensile force in face-to-face bonding which prevents obtaining maximum performance from the adhesive. In this way, only the average performance of adhesives can be taken into consideration.
Recommended
As seen to the left, using two faces on the surfaces prevents the bond from tensile force exposure and allows it have good performance.
Recommended
Variable thickness enables a uniform bond deformation throughout the adhesive film and provides the best adhesive performance.
