One component Polyurethane Translucent Adhesive for Corner Angle Frame Assembly
∎Product Description
● Polyurethane Adhesive Translucent PU-1838 is a one-part, fast-hardening translucent, solvent-free moisture curing polyurethane adhesive which, once hardened, transforms into a very strong-grip adhesive with excellent resistance to water, temperatures, weathering and ageing conditions. Due to the excellent filling properties, it is suitable for use in beading/cord applications.
● PU-1838 Designed for water-resistant bonding of wooden elements where a fast mechanical hold is necessary (10 minutes of clamp hold at room temperature) in order to permit working of hand-manufactured articles.
Suitable for structural strong-grip bonding of wooden elements on both porous and non porous substrates. Particularly useful and practical for high mechanical resistance assembly and outdoor applications.
∎Key Features
● Excellent adhesion on numerous substrates
● Easy-to-use
● Solvent free – Odourless
● Weathering resistance according to DIN 204 D4

●All surfaces to be bonded must be perfectly clean, dry and free from dust, grease, oils and debris.
●Cleaning of non-porous substrates using a lint free cotton cloth and organic solvent. Cleaning of porous substrates using a steel wire brush to remove loose particles.
●Apply PU-1838 on one side with a caulking gun or spread on substrate with a spatula.
The high viscosity holds elements to be bonded in position, the use of clamps however sometimes is
recommended. To achieve optimum performance it is important to have a very thin layer of PU Adhesive Translucent PU-1838 between the substrates, Couple substrates within 2 minutes. Slight moistening of substrates improves curing rate and gap filling characteristics as adhesive foams up to penetrate the bond cavity.
