Carboxyl-modified Vinyl Chloride from Kunshan Pg Chem Co., Ltd. is a vinyl chloride-vinyl acetate-maleic acid terpolymer supplied as a white, free-flowing powder with a K value of 45-47 and a glass transition temperature of approximately 74°C. The grade VAMA formulation contains 86±1% vinyl chloride, 13±1% vinyl acetate, and 1±0.2% maleic acid, with a carboxyl functionality of 1±0.2% by weight, delivering a transparent, colorless solution in ketone solvents. Its apparent density is 0.5 g/ml, and it achieves 100% passage through a 60-mesh sieve, with a molecular weight of about 27,000 as calculated from viscosity number data.
The resin’s carboxyl groups provide strong adhesion to metals, particularly aluminium foil, as well as to PVC, ABS, paper, textiles, and concrete, while offering excellent resistance to water, oils, esters, acids, alkalis, and salt solutions. It forms colorless and transparent or slightly yellowish solutions at 25% concentration in MEK/toluene blends, with volatilization limited to 1% and impurity particle count capped at 20 per 100 grams. Whiteness is rated at a minimum of 80, conforming to GB2913-82 standards.
VAMA grade is primarily used in air-dry finishes for maintenance, marine, and metal coatings, as well as aluminium foil varnishes, can-sealing paints, shoe adhesives, and screen-printing inks. It is also employed in heat-sealing packaging coatings, where it lowers sealing temperatures and increases bond strength, and in electrochemical aluminium paints and thermal transfer adhesives. Packaged in 25 kg kraft bags lined with PP and PE inner layers, the resin has a shelf life of one year from production when stored in dry, ventilated conditions away from direct sunlight and moisture.

Before ordering, confirm the resin’s carboxyl functionality and K value, as these directly impact adhesion and film-forming properties. Request a certificate of analysis for the specific batch to verify compliance with the listed quality standard XHQB-6, and check for any additional third-party certifications relevant to your industry, such as RoHS or REACH.
Discuss logistics terms, including Incoterms (e.g., FOB or CIF), lead times, and packaging options. The standard packaging is 25 kg kraft bags with PP and PE inner liners, but bulk or custom packaging may be available. Ensure the supplier can provide a clean, awning-covered transport vehicle to protect the resin from moisture during transit.
Arrange for pre-shipment inspection to verify particle size distribution, solution clarity, and whiteness. Request test reports for volatility, impurity count, and molecular weight to ensure consistency with your application requirements. Document all quality checks and retain samples for reference, as the resin’s performance in coatings and adhesives depends on these parameters.
