| Product description: VINNAPAS® 446 ND is a dispersion used as a bonding agent and a polymer modifier for cement based mixes. Properties: VINNAPAS® 446 ND is a dispersion based on vinyl acetate and ethylene. The product is stabilized by protective colloid. Special features: VINNAPAS® 446 ND meets ASTM C 1059 – 86 requirements for Type I and II Latex Bonding Agents. It is produced without using organic solvents and/or plasticizer donors. Application: VINNAPAS® 446 ND exhibits a high compatibility towards cement and its effect on cement setting is marginal. It can be used to formulate very workable and ductile mortars with very good adhesive properties, accompanied by high cohesive strength. Therefore, this product can be used as an organic binder for cement mortars such as water proofing membranes, 2-component tile adhesive and concrete repair mortars. VINNAPAS® 446 ND offers a superior balance of adhesive /cohesive properties, which is advantageous in the use as a general purpose bonding agent. VINNAPAS® 446 ND can be used to improve the adhesion to various substrates like concrete, masonry, polystyrene and exterior sheathing. The impact resistance and the flexibility of a cementitious base coat are improved. In gypsum joint compounds, VINNAPAS® 446 ND improves adhesion and imparts better workability.
