Sikafloor-263SL (AB) RAL1001 | MCT CHEMICALS | SIKA PAKISTAN

DESCRIPTION
Sikafloor®-263 SL is a two-component, versatile binder made from epoxy resin. It has a total solid epoxy composition as per the Deutsche Bauchemie e.V. testing method. This product should only be applied by experienced professionals. Sikafloor®-263 SL is designed for use in self-smoothing and broadcast systems applied to concrete and cement screeds subjected to normal to medium wear, such as storage areas, assembly halls, workshops, garages, and loading ramps. The broadcast system is particularly suitable for multi-story and underground car parks, maintenance hangars, and wet process areas, such as in the beverage and food industries.
