Processing

1
Stir the RTV base
Homogenize the RTV base before adding the catalyst — avoid sedimentation of fillers.
2
Dosing the catalyst
Accurate dosing: typically 5% w/w (see TDS for exact value). Dose by weight — volumetric dosing is inaccurate.
3
Mix Carefully
Low-speed stirrer — until no streaks are visible (homogeneous color).
4
Degas
30–50 mbar vacuum for bubble-free curing.
5
Processing
Pour, smooth, or apply within the pot life — pot life depends on the catalyst and temperature.

Frequently Asked Questions about CATA 83

Practical application and design questions — answered by SILITECH.

Bluesil Catalyseur 83 (40 g): Special catalyst for Bluesil RTV 3325 P — liquid-pasty, yellow, for impressions of vertical or large models (archaeology, paleontology, decoration). Main applications: archaeological replicas, paleontology, decoration.

Standard dosage is 5 parts catalyst per 100 parts RTV base (5% w/w). The exact dosage affects the pot life and demolding time — see the TDS for the exact values. Important: too little catalyst leads to incomplete crosslinking, too much catalyst dramatically shortens the pot life and can impair the final properties. Stir both components thoroughly before mixing.

Store in the unopened original container in a dry, cool place — typically standard between +5 and +30 °C, exact values see TDS. Consult the Safety Data Sheet (SDS) before use. Observe the expiration date on the packaging — Elkem guarantees the sales specifications only up to the stated date.
