Product Description

Description

Capatue^TM ADP-W452 is an adhesion promoter for aqueous systems. The main chemical composition is an epoxy-based aqueous silane oligomer with 50% active ingredient by weight and the remaining 50% water.
This product is mainly used to improve the adhesion and water resistance of waterborne coatings such as waterborne epoxy, acrylic emulsion, styrene-butadiene emulsion and polyurethane aqueous dispersion, and adhesives to inorganic materials such as glass and metal and polar substrates.
Or as an excellent high-performance layered material adhesion promoter to enhance the adhesion between inorganic materials (glass, minerals and metals) and organic polymers (hot solids, thermoplastics and elastomers), improve the mechanical strength of the material.

Product Features

1. Applicable to one-component aqueous system: This product can not only be used in an aqueous environment, but also contains half of the water itself. It can be stably existed in an aqueous system for about 1 year under the conditions of pH 4~9 and 5% active concentration, and is particularly suitable for use in an aqueous polymer system.
2, safety and environmental protection: high flash point, can be used in high temperature environment, fire source or static area, will not release flammable organic volatile VOC.
3, easy to use: direct use, no pre-hydrolysis.

 

Applications and Performance

1. Surface treatment of inorganic materials: primers for metal surface treatment liquids, glass and metal substrates, etc.;
2, water-based adhesives: a variety of water-based automotive laminate adhesives, furniture laminate adhesives and flocking plastics;
3, water-based paint: a variety of waterborne epoxy, polyurethane, acrylic water-based industrial coatings, inks.
4. Water-based polymer additive: directly added to the water-based resin to improve the adhesion and water resistance of the resin.

 

Usage

This product contains 50% water, which can be directly added to the aqueous system and dispersed at high speed. The dosage is about 0.5-5%. The optimum amount is determined experimentally.

 

Notes

This product has a good effect on the substrate with active silanol on the surface ( glass, ceramics and metal), but it is generally effective for low-polarity plastics and resin substrates. And have no effect for non-polar and low-surface materials such as PP and PE
This product has a good effect in baking varnish. It takes time to use the product under self-drying conditions. It is more suitable to test adhesion and water resistance one week after curing.

 

Packing

This product is available in 25kg plastic pail, 200L steel drums and 1000L immediate bulk container.

 

Storage and Shelf Life

Should be stored in dry, cool, ventilated room; keep away from water, moisture, high temperature and fire. This product has a shelf life of at least 12 months if stored in tightly closed original container at room temperature. 
If this product is kept beyond the shelf life recommend on the product label, it is not necessarily unusable, but a quality control should be performed on the properties relevant to the application.
