Product Description

LOCTITE® 435™ brings the flexibility and shock resistance of a rubber-toughened cyanoacrylate — the same category as LOCTITE® 410™— but at a dramatically lower viscosity (100–250 mPa·s versus 410's 1,700–5,000), making it a better fit where the adhesive needs to wet into tighter gaps or bond thinner sections without pooling. It bonds a wide range of materials, including metals, plastics, and elastomers, as well as porous and absorbent materials like wood, paper, leather, and fabric. What sets 435™ apart in this family is that it's been tested to Henkel's protocols based on ISO 10993 biocompatibility standards, intended to assist in selecting products for medical device applications — a distinguishing factor if your buyers are in med-tech manufacturing rather than general industrial assembly.

Product Characteristics

How It's Used

Bond surfaces should be clean and free from grease. 435™ performs best in thin bond gaps around 0.05 mm. Excess adhesive can be dissolved with LOCTITE® cleanup solvents, nitromethane, or acetone.

LOCTITE® 435™ is not recommended for pure oxygen or oxygen-rich systems, or as a sealant against chlorine or other strong oxidizers.

Storage

Store in the original, unopened container in a dry location. Optimal storage is 2°C to 8°C — storage below 2°C or above 8°C can affect product properties. Material removed from the container should not be returned to it once it may have been contaminated during use.
