01 · Product overview
Reliable water repellency with reactive Si-H chemistry
SilibaseMH-8484 is a high-efficiency, anhydrous silicone fluid based on polymethylhydrogensiloxane and end-capped with trimethylsiloxy groups. It can form a thin, continuous cured film on fine particles or substrates to improve water repellency, dryness and anti-caking performance.
For gypsum board and plaster products, it is normally added to the mixing or gauging water rather than used as a surface treatment. It is also suitable for powders, textiles and sealing parts, and can act as a reactive component in silicone crosslinking systems. Dosage and curing conditions should be confirmed by application trials.

Alternative evaluation against widely searched market grades
The comparison below summarizes the four supplied TDS documents for product search, sourcing and sample evaluation. It does not state that the specifications are identical.
Momentive TSF484
Common search termsTSF484 equivalent · TSF484 alternative · silicone hydride fluid
- TDS product family
- Silicone hydride fluid
- Supplied TDS evidence
- The TDS highlights excellent water repellency with moderate softness but does not publish viscosity or hydrogen-content values.
- MH-8484 evaluation point
- Evaluate by product family and water-repellent use, then reconcile the latest TDS and batch COA for both materials.
WACKER SILRES BS 94
Common search termsSILRES BS 94 alternative · SILRES BS94 replacement · BS 94 equivalent
- TDS product family
- Anhydrous polymethylhydrogensiloxane
- Supplied TDS evidence

Alternative selection FAQ
Can SilibaseMH-8484 be evaluated as an alternative to TSF484, SILRES BS 94, BLUESIL WR 68 or MHX-1107?
They belong to the same or a closely related silicone hydride / polymethylhydrogensiloxane family and overlap in gypsum and powder water-repellent uses, so comparative sample testing is appropriate. Specifications and process conditions are not identical.
What should be compared before replacement testing?
Compare hydrogen content, viscosity, volatile content, flash point, dosage, cure or dispersion method, substrate compatibility, packing and the latest safety information.
