This polyester stone adhesive by General Cehmical is suited for a variety of purposes. Polyester resin adhesives are chemically inert and offer extended durability, feature high-reactivity rapid hardening no withdrawal from substrate materials during reticulation, and a modest shrinkage during hardening (1 to 5%). This adhesive is the culmination of GENERAL® Chemical Engineering’s extensive knowledge and experience in the use of polyester resins with marble and natural stone. GENERAL is one of the highest quality products available on the market today because are chosen only very high quality rough materials and are selected only suppliers who confirm strict criteria. This quality control process assures consistency of the physical and mechanical properties of the product. The mineral fillers used in GENERAL adhesives are carefully monitored to ensure purity, inertia and proper granular dimensions which together form a durable and consistent product. Continuous research and innovation enable GENERAL® Chemical Engineering to respond to the needs of the market with a wide range of products.

How To Prepare General Chemical Polyester Stone Adhesive

For best results with this polyester stone adhesive mix 2% to 3% of the catalyst (dibenzoyl peroxide) with the adhesive; the paste formula make easy to measure. A homogeneous mixing will facilitate uniform catalysis. The catalysis rate is effected by temperature and by the propotion/quantity of catalyst. An excess of hardener/catalyst will increase the hardening speed, but weakens the adhesive seal. The surfaces to be treated/glued must be clean and dry; porosity and light roughness of the surface favour the best adhesion.

NOTE:The hardened/cured adhesive is completely workable (grinded, polished, sanded, buffed etc.) after 4 to 5 hours (better is after 24 hours). Laboratory tests evidence that the adhesive, once hardened and properly cured, resists also to temperatures lower than 0°C (32°F). Because of the difference of dilatation or/and contraction between the support (marble, granite, stone), temperature well below 0°C (32°F) can anyway be cause of weakening or separation of the material.
