Гидроксипропил метакрилат химические свойства, назначение, производство
Описание
Hydroxypropyl methacrylate(HPMA) is a clear, colorless liquid with a pungent, sweet odor. The product contains low levels of a polymerization inhibitor along with small amounts of methacrylic acid, and propylene oxide. HPMA is used in the manufacture of acrylic polymers for adhesives, inks, and coatings for automotive, appliance and metal applications. The added hydroxyl groups improve adhesion to surfaces, incorporate cross-link sites, and impart corrosion, fogging, and abrasion resistance.
Химические свойства
Clear colorless liquid
Использование
Monomer for acrylic resins, nonwoven fabric binders, detergent lubricating-oil additives.
прикладной
2-Hydroxypropyl Methacrylate (HPMA) used in the preparation of solid and emulsion polymers, acrylic dispersions in combination with other (meth) acrylates, which are used in various industries, especially for textile coatings and dressings. HPMA is widely used in the production of acrylic polyols for automotive components, refurbishment coatings, and industrial coatings. HPMA is also used as a comonomer in styrene-based unsaturated polyesters, PMMA-based acrylic resins, and vinyl ester formulations in anchor bolts and chemical anchors.HPMA is particularly useful as a hydrophobic hydroxy monomer in the manufacture of sealants for vacuum impregnation of cast aluminum components. HPMA is also widely used in the production of flexible UV-curable photopolymer printing plates.
Общее описание
White liquid with a light unpleasant odor. May float or sink in water.
Профиль реактивности
2-Hydroxypropyl methacrylate polymerization: May polymerize when hot or when exposed to ultraviolet light and free-radical catalysts [USCG, 1999].
Угроза здоровью
Inhalation causes coughing and irritation of nose and throat; lung injury may occur. Ingestion causes irritation and burning of mouth and stomach. Contact of vapor with eyes causes irritation. Liquid may cause severe eye burns and irritation of skin.
Пожароопасность
Behavior in Fire: Compound may polymerize when hot and burst container.
Безопасность
2-Hydroxypropyl Methacrylate (2-HPMA) is a combustible substance. With intense healing, it forms explosive vapors with air. Vapors are heavier than air and may spread along with floors. In the case of fire, the formation of harmful gaseous products is possible. Contact with skin may cause an allergic reaction. When working with 2-Hydroxypropyl Methacrylate (2-HPMA), sanitary rules for organizing technological processes and hygienic requirements for production equipment must be strictly observed.
