REX LITH TRANSPARENT POLYESTER PUTTY

What is MASILLA POLIESTER REX LITH TRANSPARENTE and why choose it

MASILLA POLIESTER REX LITH TRANSPARENTE by König Iberica is a solvent-based, two-component polyester filler designed for demanding repairs on interior surfaces. In its transparent version (Rex-Lith 151), it offers very high hardness, minimal shrinkage and the possibility of polishing, making it especially suitable for rebuilding corners, edges and filling deep defects where a subtle or clear appearance is needed. Information in this description is based on publicly available technical data from the Rex-Lith range and may not be fully verified for this specific packaging; always check the official technical data sheet from König before use.

Main features

• Two-component polyester filler (filler + hardener paste).
• Solvent-based formulation with very little shrinkage (approximately 1–2%) after curing.
• Extraordinarily hard and mechanically resistant once cured, suitable for surfaces subject to heavy use.
• Transparent version (Rex-Lith 151), suitable for clear or translucent repairs and can be polished according to manufacturer information.
• Fast processing and curing: working time of about 4–8 minutes, full hardening in approximately 20–30 minutes depending on temperature and hardener amount.
• Can be sanded, planed, milled and otherwise machined after curing.
• Low contraction helps maintain the shape and volume of the repair.
• Can be overcoated with 1K and 2K lacquers and varnishes; for exterior use the repair must be protected with a UV-stable topcoat.
• Compatible with König touch-up products for tinting if a specific shade is required (information based on general Rex-Lith documentation, not individually verified for this kit).

The transparent Rex-Lith polyester filler is formulated for structural and cosmetic repairs where high mechanical resistance and discreet appearance are required.

Recommended applications

• Repair of surfaces subject to heavy and continuous use (based on Rex-Lith technical sheet).
• Rebuilding missing material on corners and edges of panels, furniture and fittings.
• Filling deep holes, gouges and pressure marks in wood, laminate and other compatible substrates.
• Repairs on interior components made of wood, plastics (excluding PE, PP and PTFE), metal, marble, stone and polyester.
• Localized reconstruction of cut-outs for hardware or fittings where a strong and stable filler is required.
• Situations where a transparent or polishable filler is advantageous, such as clear finishes or visible edges.

General guidance for use (non-verified summary)

1. Ensure the substrate is clean, dry, free from dust, grease and loose particles.
2. Mix the required amount of filler with the appropriate proportion of hardener paste until a homogeneous mixture is obtained (consult the official instructions for exact ratios).
3. Apply the mixture to the damaged area, pressing firmly to fill completely; slightly overfill to allow later leveling.
4. Allow to cure for the time recommended by the manufacturer (usually around 20–30 minutes at room temperature).
5. Once hardened, level and shape by scraping, sanding, planing or milling.
6. If necessary, finish with lacquers or varnishes compatible with polyester fillers. For exterior exposure, always apply a protective topcoat.

Section 14 – Transport information (summary)

The transparent Rex-Lith polyester filler is classified as a hazardous material for transport in some markets, due to its solvent-based polyester composition and the presence of organic peroxides in the hardener, according to information from international distributors. This section is a general, non-verified synthesis and does not replace the official SDS transport section.

• UN number, proper shipping name, hazard class and packing group: These details depend on the specific formulation and packaging and must be obtained directly from the official safety data sheet (Section 14) issued by König.
• Transport by road/rail (ADR/RID), sea (IMDG) and air (IATA): The product and/or its hardener may be regulated; some distributors specify ground shipping only for standard deliveries. Always follow the indications on the SDS and transport labels.
