RUVIL VP3238 is used to modify mixtures containing hydraulic binders, whenever a high thixotropy system is required.
Due to its particular chemical-physical constitution, RUVIL VP3238 improves the adhesion to substrates, makes longer the open time and lower the contents of water to the mixtures.
RUVIL VP3238 is particularly indicated for the premixtures such as tiles adhesives
with high resistance to the vertical slide. Even a small quantity of RUVIL VP3238 to the premixture is quite enough to improve the adhesion and heat resistance. For low thickness tiles adhesives, we suggest to add 1% to 4% of RUVIL VP3238 to the premixtures.
Mortars for thermal insulation
The addition of RUVIL VP3238 to the mortar gives a good workability to the end product as well as an excellent adhesion and water resistance.
To prepare adhesives for thermal insulation and mortars for finishing, we suggest to add 2% to 5% of RUVIL VP3238.
Mortars containing RUVIL VP3238 have as main properties good adhesion and workability; this is why RUVIL VP3238 is indicated for repairing mortars, mainly due to its particular rheologic behaviour.
RUVIL VP3238 is delivered in paper bags of 25 kg and big bags of 500 kg.
RUVIL VP3238 must be stored in a dry and cool warehouse. Pallets must not be overlapped due do the thermoplasticity of the polymer.
Packing must be well closed after use, in order to avoid the atmospheric humidity which may cause the caking of the redispersible powder.
