CONSTITUTION : PVA TXP-20 is an aqueous non- ionic emulsion of plasticized poly vinyl acetate .
NATURE : Non- ionic
APPEARANCE : White milky viscous emulsion.
PH : 4.5 - 5.5
VISCOSITY : 130-180 Poise at 25C (Rion viscotester VT - 04)
SOLID : 40% +/- 2%
SOLUBILITY : Soluble in hot and cold water in all proportions.
STABILITY : Stable for long time. It is also stable in weak acid, and alkalis, optical whitening agent.
PROPERTIES : PVA TXP-20 leaves a transparent film on drying and does not effect or tint the base material. There for it can be safely used for white as well as dyed finishing of textile. PVA TXP-20 is compatible with various resins and softening agent and gives full soft and elastic in handle.
