Product Description
Taftbond HM969G is a green coloured neoprene-based spray grade contact adhesive which has great versatilities in bonding a wide range of substrates with good adhesion. The cured adhesive has good heat and aging resistance. It bonds well to most substrates like stainless steel, natural rubber, most plastics (except PE, PP & Teflon), wood, rock wool, veneers, and PU foams. The cured adhesive has good water, heat and non-aromatic fuels resistance.
Features
- Fast curing and good bonding strength
- Bonds a wide variety of substrates
- Sprayable, easy application and consistent adhesive thickness

Surface Preparation
To achieve optimal adhesion strength, it is highly recommended for substrates to be adequately abraded and cleaned prior to any bonding applications. Surfaces intended for bonding must be free from dust, oil/grease and any loose contaminants. Do not use oil-based cleaners, which serve as a barrier between the adhesive and the substrates, impeding effective bonding.
Application
- Taftbond HM969G is ideal for applications using conventional air assisted spray equipment.
- Roll the drum prior to using, preventing any possible sedimentation that may occur during storage.
- Spray a moderate coating to both surfaces, ensuring at least 90% of each surface is coated.
- Porous or absorbent substrates may require 2 coats of adhesive. Apply the second coat straight away after the first layer tacked off.
- It is critical to allow adhesive to tack free before bonding. Failure to do so results in solvent entrapment, leading to possible delamination.
- A fresh coat of adhesive is recommended if substrates are not bonded beyond the open time.
- Once adhesive is ready, align surfaces and bond lightly, applying firm pressure from centre of panel towards the edge carefully, avoiding any air entrapments during the process.
- Apply roller pressure after this process to ensure both surfaces are completely bonded.
Limitation
- Not suitable for bonding PP (Polypropylene), PE (Polyethylene), Teflon, Silicone and expanded polystyrene foam. For all other substrates, ensure sufficient trials are conducted before using commercially.
- Not recommended for bonded parts intended for permanent submersion in water.
- Not recommended for exterior use.
Important Note
