102HT - Hi-Temp Toughened Structural Adhesive

102HT Hi-Temp Toughened Structural Strength -

Rhino 102HT is a toughened, high temperature use structural epoxy adhesive designed 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 102HT bonds with an immediate high tack consistency, and offers a quick cure when used at ambient temperatures ranging from 60°F (15°C) to 95°F (35°C). The working life at 77°F (25°C) is 60 minutes (working time increases with lower ambient temperatures), with full cures occurring between 12 – 14 hours depending on cure temperature.

Description

Rhino™ 102HT is a toughened, high temperature use structural epoxy adhesive designed 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. 102HT bonds with an immediate high tack consistency, and offers a quick cure when used at ambient temperatures ranging from 60°F (15°C) to 95°F (35°C). The working life at 77°F (25°C) is 60 minutes (working time increases with lower ambient temperatures), with full cures occurring between 12 – 14 hours depending on cure temperature.

Unlike most epoxy adhesives, 102HT adhesive cured at ambient temperatures provides heat resistance well in excess of most engineering limits with an HDT of 105º C (220°F ). The material mixes at 100:35 by weight (resin to hardener). The convenient color-coded components form a uniform color when properly mixed. Rhino 102HT adhesive is designed for high production meter/mix ram dispensing and although highly thixotropic, it offers very fast application rates. 102HT adhesive is solvent free, and 100% solids.

Suggested Uses

Use Rhino 102HT adhesive to bond fiberglass to itself, and other materials such as concrete, metal, wood, and many plastics. Rhino 102HT adhesive is highly recommended as a “tack coat” for applying epoxy resin saturated reinforcement materials to vertical and overhead substrate such as concrete, or steel in the areas of seismic retrofit and structural upgrades.

Additional Benefits

Rhino 102HT 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 102HT adhesive results in minimal degradation of the cured adhesive’s physical properties as compared to epoxy systems not containing the proprietary formulation constituents of 102HT adhesive. This technology offers the fabricator not only a superior adhesive today, but more importantly, increased product life and long term durability.

 

Surface Preparation

All surfaces should be mechanically abraded, or, in the case of fiberglass laminate(s), the use of peel ply on the bonding surfaces is acceptable. All dust, grease, and standing water must be removed prior to the application of 102HT Adhesive.

Recommended Curing of Rhino 102HT Adhesive
