N85 Functional Filler CAS 61790-53-2 for Putty and Filler Compound
N85 Functional Filler CAS 61790‑53‑2 is high‑purity natural siliceous earth processed via fine grinding and multi‑stage particle classification. Designed for building putty and filler compound. Its unique porous particle structure optimizes mixing workability and trowelling performance. It improves sandability of dried putty layer, reduces shrinkage cracking risk, enhances adhesion and weather resistance. Compatible with cement, gypsum and latex binder systems, it helps reduce comprehensive raw‑
Overview
Our N85 Functional Filler CAS 61790‑53‑2 is refined from premium diatomite ore through impurity removal, fine milling and precise particle‑size screening. This economical mineral extender is customized for architectural putty and filler compound. Oversized grit particles are strictly controlled to avoid scratch marks during surface sanding. It can be compounded with calcium carbonate, talcum powder and cement to balance construction performance and finished‑film mechanical indicators for wall putty systems.
Key Features
- Optimize trowelling and mixing workability, deliver smooth construction feel for putty and filler compound.
- Greatly improve sanding performance of cured putty layer, easy for subsequent polishing treatment.
- Reduce drying shrinkage, effectively lower cracking risk for thick‑layer putty application.
- Boost adhesion strength and weather resistance, upgrade durability of interior and exterior wall putty.
- Good compatibility with cement, gypsum, redispersible polymer powder and other putty raw materials.
- Chemically inert, stable under alkaline environment of building putty, no adverse side effects.
Main Applications
- Interior wall water‑based putty formulation
- Exterior weather‑resistant wall putty and skim coat
- Gypsum‑based filler compound for building decoration
- Cement‑based repair putty and joint filling compound
- General‑purpose building filler requiring good sanding property
Usage Recommendation
- Typical dosage: 5‑20 % by weight, adjust according to construction feel, crack‑resistance and sanding requirement.
- Add together with other mineral powders in dry‑mixing section for uniform premixing.
- Strictly control water‑to‑powder ratio according to formula specification; excessive water will increase shrinkage risk.
- Can be compounded with calcium carbonate to optimize formula cost.
- Complete lab test for workability, shrinkage and sanding performance before mass production.
Storage & Package
- Store in dry and ventilated warehouse, keep bags tightly sealed against moisture absorption.
- Standard package: 25kg woven bag with inner PE liner.
