1 : 1 parts by volume (also refer to mixing instructions)

Values of the metering chart are valid for a 10 % hardener solution using Part C (Hardener).
   
Part A (Resin) is activated by Part B (Accelerator). The necessary quantity of Part B (Accelerator) is determined according to the metering chart above considering the ambient and/or substrate temperature and the speed of reaction time required for the work.
 
~20 litres Part A (Resin) are mixed with between 0,5 % up to 10 % of Part B (Accelerator) (0,14 L to 2,0 L)

Ambient air temperature

+5 °C min. / +40 °C max.

Substrate temperature

+5 °C min. / +40 °C max.

Curing time

~2–10 minutes (Dependent on substrate temperature, plus the amount of accelerator and hardener used)

MIXING

Mixing sequence

1. Resin solution

Determine the required quantity of accelerator (Part B) from the accelerator metering chart (Table 1). As a guide: 0,5 % up to 10 % (0,14 to 2,0 litres). Mix thoroughly with 20 litres of Part A (Resin).

2. Hardener solution

Pour ~18 litres of water in a clean container. Dissolve ~2,0 kg of Part C (Hardener) powder in the water. Stir with a mixer at low speed the hardener solution thoroughly until Part C is completely dissolved.

CLEANING OF EQUIPMENT

Clean all tools and application equipment in accordance with the Product Data Sheet for the Sika® Injection Cleaning System.

Short interruptions of injection work
Mixing equipment can be cleaned with water immediately after use. Hardened material can only be mechanically removed. The 2-component acrylate injection pumps have an additional rinsing pump for cleaning.
