Water based acrylic emulsion curing compound

CHRYSO®Cure Acrylic is a is a water-based slightly viscous acrylic emulsion solution which dries to a colourless stain free surface when applied to concrete.

CHRYSO®Cure Acrylic complies with the performance specifications of ASTM C309.

Uses

CHRYSO®Cure Acrylic is an economical method to assist in efficient concrete curing.

  • The product acts chemically with the hydroxides produced by the hydration of cement to form a dense porefilling crystalline structure that in turn reduces the water evaporation rate from the concrete surface.
  • The presence and retention of water in concrete is essential to ensure adequate strength development and minimise initial plastic shrinkage crack development.
Features

CHRYSO®Cure Acrylic is compatible with water retaining structures (potable water).

  • Economical, single application reduces the incidence of shrinkage cracks.
  • Promotes better strength gain characteristics.
  • Useful as a dust-proofer and surface hardener (particularly on floor areas).
  • No film breakdown period involved.
  • Does not interfere with subsequent concrete surface treatments (paints, emulsions, sealants adhesive, renders, tile adhesives etc.).
Typical Properties
Physical State Liquid
Specific Gravity (25˚ C) >1
pH (where a pH measurement is possible): 10
Solubility in water dilutable

It should be noted that while CHRYSO®Cure Acrylic is effective in improving moisture retention, the Curing efficiency Index is lower than that of conventional resin film-forming membranes.

Therefore, where a high curing efficiency index is required, one should select a resin film forming membrane compound (ask a CHRYSO® technical sales representative for more information on other products within the CHRYSO®Cure Acrylic range).

Bear in mind that should subsequent surface coatings be required, the time lapse involved with resin based membranes is subsequently longer.

Directions For Use

The recommended application rate (preferably by a spray applicator) is 5 m2/ ℓ.
Over application may result in a slightly glassy concrete surface finish.

Horizontal surfaces:
CHRYSO®Cure Acrylic should be applied to freshly cast horizontal surfaces immediately after the initial surface water sheen has disappeared.

Vertical surfaces:
CHRYSO®Cure Acrylic should be applied immediately to the ‘as stripped’ concrete surface (there is no prerequisite to damp down the surface prior to application).

Equipment:
All spraying equipment should be cleaned with water after use.

Packaging

25 litre metal or plastic drums.
200 litre metal or plastic drums.
