Sikadur®-30 LP

Thixotropic adhesive for bonding reinforcement

Sikadur®-30 LP is a thixotropic, structural 2-component adhesive, based on a combination of epoxy resins and especially designed for use at higher temperatures between +25 °C and +55 °C. Suitable for use in hot and tropical climatic conditions.

Sikadur®-30 LP has the following advantages:
  • Long pot life
  • High temperature resistance at elevated curing temperatures
  • Easy to mix and apply
  • No primer needed
  • High creep resistance under permanent load
  • Very good adhesion to concrete, masonry, stonework, steel, cast iron, aluminium, timber and Sika® CarboDur® Plates
  • Hardening is not affected by high humidity
  • High strength adhesive
  • Thixotropic: non-sag in vertical and overhead applications
  • Hardens without shrinkage
  • Different coloured components (for mixing control)
  • High initial and ultimate mechanical resistance
  • High abrasion and shock resistance
  • Impermeable to liquids and water vapour

Material temperature

Sikadur®-30 LP must be applied at temperatures between +20 °C and +40 °C.

Ambient air temperature

+25 °C min. / +55 °C max.

Dew point

Beware of condensation.
Substrate temperature during application must be at least 3 °C above dew point.

Substrate temperature

+25 °C min. / +55 °C max.

Substrate moisture content

Maximum 4 % pbw
When applied to mat damp concrete, brush the adhesive well into the substrate.

Pot Life

TemperaturePotlifeOpen time
+25 °C~60 min~90 min
+55 °C~30 min~60 min

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 components A and B before mixing them (not below +5 °C).

 
Application steps

SUBSTRATE QUALITY

See the Product Data Sheet of Sika® CarboDur® Plates and Sika® CarboDur® BC rods.

SUBSTRATE PREPARATION

See the “Method Statement for Sika CarboDur® Externally Bonded Reinforcement” and the “Method Statement for Sika CarboDur® Near Surface Mounted Reinforcement”.

MIXING

Pre-batched units:
Mix components A and B together for at least 3 minutes with a mixing spindle attached to a slow speed electric drill (maximum 300 rpm) until the material becomes smooth in consistency and a uniform grey colour. Avoid aeration while mixing. Then, pour the whole mix into a clean container and stir again for approximately 1 more minute at low speed to keep air entrapment at a minimum. Mix only that quantity which can be used within its potlife.

 

CLEANING OF EQUIPMENT

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