Sika® Primer EP-20 TR

Product Description

Sika® Primer EP-20 TR is an economical, two-component, low viscosity epoxy-based primer. Thanks to its high penetration ability, it penetrates deeply into the surface and provides excellent adhesion strength. It provides reliable floor preparation for concrete, screed and epoxy based systems. It is easy to apply thanks to its low viscosity, increases the application speed with its short waiting time and provides multi-purpose use. Areas of Use In priming concrete sub-surfaces In priming cement screeds Epoxy mortar and coating systems On normal and highly absorbent surfaces As a primer in 2-component spray polyurethane / polyurea applications As a primer on polyurethane / polyurea applications, before ceramic adhesive Advantages Low viscosity structure High penetration feature Excellent adhesion strength Easy and fast application Short waiting time Multi-purpose use Economical solution Packaging Information Component A (Resin): 18.96 kg tin can Component B (Hardener): 5.04 kg tin can A+B Total: 24 kg ready-to-use set Color Information Component A (Resin): Brownish – transparent, liquid Component B (Hardener): Transparent, liquid Product Information Chemical Structure: Epoxy based Shelf Life: 24 months from production date Storage Conditions: In original, unopened and undamaged packaging in dry environment Must be stored between +5 °C and +30 °C Density (+23 °C) Component A: ~ 1.6 kg/l Component B: ~ 1.0 kg/l Mixture: ~ 1.4 kg/l Solids Content: ~100% (by volume) ~100% (by weight) Technical Information Mixing Ratio A : B = 79 : 21 (by weight) Application Conditions Outdoor Temperature: +10 °C / +30 °C Surface Temperature: +10 °C / +30 °C Relative Humidity: Max. 80% Surface Moisture Content: Measurement with Sika Tramex: < 6% CM measurement or oven dry: < 4% According to ASTM, there should be no moisture escape from the surface To avoid the risk of condensation, the surface temperature must be at least 3 °C above the dew point.
