Sikadur®-32 LP IN

ASTM C881-78, Type II, Grade 2, Class B+C

Epoxy resin and selected fillers

12 months from date of production

The product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +40 °C. Protect from direct sunshine.

All values at curing temperature +30 °C

Part A : Part B = 2 : 1 (by weight)

+5 °C min. / +40 °C max.

Beware of condensation.

Steel substrate temperature during application must be at least +3 °C above dew point.

+5 °C min. / +40 °C max.

Cementitious substrates must be dry or matt damp (no standing water).

Brush the adhesive well into the substrate if matt damp.

The potlife begins when the resin and hardener are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the potlife. To obtain longer workability at high temperatures, the mixed adhesive may be divided into portions. Another method is to chill parts A+B before mixing them (not below +5 °C).

~0.3–0.5 kg/m²

This figure is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.

Concrete / masonry / mortar / stone

Concrete and mortar must be at least 3–6 weeks old.

Substrate surfaces must be sound, clean, dry or matt damp. Free from standing water, ice, dirt, oil, grease, coatings, laitance, efflorescence, old surface treatments, all loose particles and any other surface contaminants that could affect adhesion of the bonding agent.

Steel

Surfaces must be clean, dry, free from oil, grease, coatings, rust, scale, all loose particles and any other surface contaminants that could affect adhesion of the bonding agent.

Wood

Substrate surfaces must be sound, clean, dry and free from dirt, oil, grease, coatings, all loose particles and any other surface contaminants that could affect adhesion of the bonding agent.

Polyester / epoxy / ceramics / glass

Surfaces must be clean, dry, free from oil, grease and any other surface contaminants that could affect adhesion of the bonding agent.

Concrete / masonry / mortar / stone

Substrates must be prepared mechanically using suitable abrasive blast cleaning, needle gunning, light scabbling, bush hammering, grinding or other suitable equipment to achieve an open textured gripping surface profile.

Steel

Surfaces must be prepared mechanically using suitable abrasive blast cleaning, grinding, rotating wire brush or other suitable equipment to achieve a bright metal finish with a surface profile to satisfy the necessary tensile adhesion strength requirement. Avoid dew point conditions before and during application.

Wood

Surfaces must be prepared by planing, sanding or other suitable equipment.

Polyester / epoxy

Surfaces must be prepared by abrading using suitable equipment.

Ceramics / glass

Surfaces must be prepared by abrading using suitable equipment. Do not apply to siliconised substrates.

All substrates

All dust and loose material must be completely removed from all substrate surfaces before application of the product by vacuum / dust removal equipment.

Prior to mixing all parts, mix part A (resin) and part B (hardener) briefly using a mixing spindle attached to a slow speed electric mixer (max. 300 rpm). Add part B (hardener) to part A and mix parts A+B continuously for at least 3 minutes until a uniformly coloured smooth consistency mix has been achieved. To ensure thorough mixing, pour materials into a clean container and mix again for approximately 1 minute. Over mixing must be avoided to minimise air entrainment. Mix full units only. Mixing time for A+B = 4.0 minutes. Mix only the quantity which can be used within its pot life.

Clean all tools and application equipment with Sika® Colma Cleaner or suitable solvent immediately after use. Hardened material can only be mechanically removed.
