1.Product Description

2.Crosslinking characteristics

There is an active vinyl group in the molecule.andionThe two epoxy functional groups in the reaction can polymerize via functional group reactions or through ionic reactions.During film formation, the epoxy groups of this product readily crosslink and cure with carboxyl groups, effectively eliminating the carboxyl groups. This reduces the water absorption rate of the coating film and improves its water resistance.The increase in crosslinking density、The swelling rate decreased.Sure.Improve the solvent resistance of the coating film and enhance mechanical strength.Additionally, its unique functional groups can effectively enhance the adhesion between the coating and the substrate.

3.Product Usage

3.1 Crosslinking agent for coatings

In terms of coatings,CR303It can be used in acrylic coatings, acrylate coatings, alkyd resin coatings, vinyl chloride resin, and other water-based coatings, significantly improving the hardness, gloss, adhesion, weather resistance, and water resistance of the coating film.

3.2 Latex adhesive

Used in adhesives and non-woven fabrics, it improves adhesion to metals, glass, cement, polyvinyl fluoride, etc., when used in acrylic emulsions; when used in synthetic latex non-woven fabrics, it enhances washability without affecting the hand feel.

4.Nature of Hazard

Harmful if inhaled, in contact with skin, or swallowed.；If accidental eye contact occurs, rinse immediately with plenty of water and seek medical advice.。
