102 - Toughened Structural Adhesive
Toughened Structural Adhesive –
Rhino™ 102 is a high strength, toughened, structural epoxy adhesive for the bonding of fiberglass to itself and many dissimilar materials. It is a two phase (toughened) epoxy resin produced using a CTBN elastomer with a flexible epoxy resin backbone for maximum stress and fatigue resistance.
Rhino™ 102 is a high strength, toughened, structural epoxy adhesive for the bonding of fiberglass to itself and many dissimilar materials. It is a two phase (toughened) epoxy resin produced using a CTBN elastomer with a flexible epoxy resin backbone for maximum stress and fatigue resistance. 102 bonds with an immediate high tack consistency, a long working life and a quick cure time. Rhino 102 may be used at ambient temperature(s) ranging from 55°F (13°C) to 100°F (38°C). The working life at 100°F (38°C) is > 2 hours (working time increases with lower ambient temperatures), with full cures occurring between 6 – 12 hours depending on cure temperature.
Unlike most epoxy adhesives, Rhino 102 adhesive cured at ambient temperatures provides heat resistance well in excess of most engineering limits with an HDT of 85º C (185°F ). The material mixes at 2:1 by volume, or 100:44 by weight (resin to hardener). The convenient color-coded components form a uniform color when properly mixed.102 adhesive is designed for high production meter/mix ram dispensing and although highly thixotropic, have very fast application rates. With low odor and toxicity, Rhino 102 adhesive is solvent free, and 100% solids.
Rhino 102 adhesive is formulated to improve the intimate bond between the epoxy adhesive and cured glass fiber laminate. This formulation technique results in increased physical properties due to better surface wetting and increased bond strength to E-glass fibers. Of equal, if not greater significance is the retention of physical properties after exposure to heat, cycle fatigue, water, expected adverse environmental reagents such as salt spray, acid rain, etc.
The formulation of Rhino 102 adhesive results in minimal degradation of the cured adhesive’s physical properties as compared to epoxy systems not containing the proprietary formulation constituents of 102 adhesive. This technology offers the fabricator not only a superior adhesive today, but more importantly, increased product life and long term durability.
Recommended Curing of Rhino 102 Adhesive
