Bison Poly Max Crystal Express is an universal, crystal clear, high-quality construction adhesive and sealant with super-fast final strength build-up for bonding, fixing and sealing funeral urns. On almost all surfaces (both, smooth, porous and non-porous surfaces). Bonding: e.g. glass, natural stone, many synthetic materials, wood, iron, aluminium, steel, stainless steel and ceramic. Once the glue has dried and hardened it is virtually impossible to open the urn.
Very high final strength
Super fast final strength build-up
For indoor and outdoor applications
Good filling capacity
Temperature resistant from -40°C to +100°C
Water and weather resistant
100% adhesive (no shrinkage)
Excellent adhesion without primer
Only apply at temperatures between +5°C and +40°C. The surface must be dry, clean and free of dust and grease.
Bonding and fixing: Correctly position material within 10 minutes and press firmly or lightly tap with a rubber mallet. If necessary, clamp or fixate heavy materials for 4 hours. Can be handled after 2 hours, the connection is now strong enough to withstand transportation or a light load. Maximum final strength after approx. 4 hours, depending on the surface (at least 1 porous material) and the ambient conditions. Sealing: Evenly apply to the bottom of the joint and tool within 10 minutes using a moistened (with soapy water without lemon) putty knife, sealant smoother, or finger. Tool the vertical joints from bottom to top. Fully cured after a few days (depending on the thickness of the layer).
Stains/Residue: Use white spirit for cleaning tools and removing wet adhesive residue. Dry adhesive residue can only be removed mechanically.
Points of attention: The following drying times are based on bonding at least one porous material and an adhesive layer of approx. 1 mm thickness. If two non-porous materials are being bonded and/or the layer of adhesive is thicker, the drying times may be substantially longer. When adhesive is applied underwater, it may turn white.
Once the glue has hardened, it is almost impossible to re-open the urn.
