1产品简介/Product Overview

优砾科 ® FT51 高性能自流平耐磨地坪砂浆是一种预拌干混水泥基自流平材料，以高强无机胶凝材料、精选级配天然耐磨骨料、矿物功能填料、低收缩改性助剂及高性能聚合物改性组分复合配制而成。本品设计用于 5–10 mm 厚度的重型耐磨自流平面层（Heavy-Duty Self-Leveling Overlayment），在新旧混凝土基层上形成致密、高强、耐磨、抗冲击的承载面层。UNIKRETE® FT51 is a pre-bagged, dry-mix cementitious self-levelling screed formulated from high-strength inorganic binders, selected graded natural wear-resistant aggregates, mineral functional fillers, low-shrinkage modifying admixtures and high-performance polymer modifiers. It is designed for heavy-duty self-leveling overlayment at a thickness of 5–10 mm, providing a dense, high-strength, wear-resistant and impact-resistant wearing surface over new or existing concrete substrates.
