Product Description
Taftbond HM232ST is a general-purpose clear contact adhesive which dries quickly to a firm bond. It is designed to adhere to a wide range of substrates with good adhesions. Bonded parts with this adhesive exhibit excellent resistance to heat and aging.
Features
- Good resistance to water, detergent soap solutions, oils and grease
- Fast curing and good bonding strength
- Bonds to most substrates
- Does not attack Styrofoam

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 HM232ST is ideal for applications using roller or brush on methods.
- Apply a moderate coating to both surfaces, ensuring at least 90% of each surface is coated.
- Porous or absorbent substrates may require 2 thin 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.
