RUDOLF RUCOLAC B-402 | Tannin-resistant additive for wood

Hello everyone:

We are the authorized distributor of RUCOLAC® B-402 wood tannin inhibitor from RUDOLF, Germany.

Pre-treatment can be performed before painting to prevent tannic acid seepage from the wood and the risk of discoloration. The following test report is provided for your evaluation.

Key testing points:

Dilute with water to a ratio of B-402:water = 15:85, and apply one and two coats respectively.

• After air drying for 7 days, soak in water for 24 hours and observe.

Test results:

• Observe the color change of the water; applying two coats will have a noticeable effect!
