S 21 construction adhesive

RECA S 21 PU assembly adhesive is an extremely fast hardening polyurethane adhesive with a paste (thixotropic) structure

Field of Application:

RECA S 21 PU assembly adhesive has been developed for bonding wood, metal, stone, concrete, plastic and insulation materials such as PU foam, PS foam, rock wool and glass wool.

Advantages:

• Fast curing, excellent gap filling properties
• Waterproof (D4)
• High tensile strength
• Suitable for bonding wood, metal, concrete, plastic and insulation material, natural stone compatible

Advice:

Press the parts being bonded together during the skin formation period (max. 2 minutes after moistening) and, if necessary, press together until functional strength is reached. The product swells slightly during the curing process. When bonding non-absorbent materials together, mist the applied adhesive with water.
Sunlight discolours the adhesive but does not affect the adhesive strength.
• Not suitable for PE, PP, PC, PMMA, PTFE, soft plastics, neoprene
• Yellowing can occur when the adhesive is exposed to UV light

• "From 24 August 2023, adequate training must be completed prior to industrial or commercial use".
