Full title and description

GOST 10772-78 — Покрытия литейные противопригарные водные. Общие технические условия. (English title: Water foundry coatings for mould paints — General specifications). National (USSR / interstate) standard specifying technical requirements, test methods, marking, packaging, storage and safety provisions for water‑based foundry (parting) coatings supplied as pastes or powders, and for their application to moulds and cores.

Abstract

This standard establishes classification, general technical requirements and test procedures for water‑based foundry parting/coating materials used in metal casting. It covers product forms (pastes and powders), required physical and performance properties (viscosity, sedimentation stability, density, abrasion resistance), sampling and acceptance rules, preparation and application instructions, packaging, storage life and basic safety/handling requirements (including references to relevant occupational safety norms and radiation safety where zirconium concentrates are used).

General information

• Status: In force / active (interstate standard introduced in 1979; maintained in standards databases with later amendments).
• Publication date: Approved 22 May 1978; date of introduction / entry into force 1 January 1979.
• Publisher: State Committee for Standards of the USSR (Gosstandart); developed under the Ministry of the Machine‑Tool Industry (developers credited in the original document).
• ICS / categories: MКС (ICS) 01.040.25; 25.220.40. OKP/industry code often cited as 41 9150.
• Edition / version: GOST 10772‑78 (original 1978 text, introduced 1979) — with later amendments recorded in official compilations (amendments published in the 1980s).
• Number of pages: Typically shown as 8 pages for the core text; some published compilations or translated editions run up to ~14 pages depending on formatting and inclusion of amendments and annexes.

Scope

Applies to water‑based foundry parting/coating materials used to separate metal and mould surfaces (anti‑adhesive/parting coatings) in metal casting operations. The standard covers both paste and powder forms, defines marking and packaging requirements, specifies sampling and acceptance testing methods and sets storage, transport and safety requirements for manufacturers, laboratories and foundry end users.

Key topics and requirements

• Classification of coatings by form and mark (pastes and powders; standard product marks defined in the text).
• Physical property limits and test methods — conditional viscosity (VZ‑4 viscometer), sedimentation stability, density, moisture content, and appearance of prepared and dried films.
• Abrasion (wear) resistance test procedure for dried coating layers on glass plates using standardized sand and apparatus.
• Preparation and mixing instructions (mixing times and recommended mixing equipment for pastes and powders; recommended dilution densities).
• Application methods — brush or spray; recommended coating thickness and drying conditions (laboratory drying and test temperatures specified).
• Marking, packaging and transport: specified container types, lining requirements, and sealing; requirements for cleaned and suitable reusable containers.
• Storage life / manufacturer guarantees — typical shelf life guidance (e.g., pastes ~6 months, powders ~12 months) and storage/temperature handling notes after cold transport.
• Safety and environmental provisions — references to occupational safety standards and special precautions when zirconium concentrates or other hazardous components are present (ventilation, PPE, wet cleaning, radiation safety references where applicable).

Typical use and users

Primary users are foundries, mold shops and coremaking operations that require water‑based parting coatings for metal casting. Other users include coating manufacturers, quality and metrology laboratories performing acceptance and routine tests, procurement/specification engineers, and regulators overseeing industrial safety and materials compliance.

Related standards

GOST 10772‑78 references and is commonly used alongside a number of safety and test standards, for example: GOST 12.1.005 (general safety requirements), GOST 12.3.002 and GOST 12.3.005 (industrial safety/health rules), GOST 1770 (measuring cylinders), GOST 2138 (molding sands), GOST 8420 (viscosity methods), plus packing/transport standards (GOST 13950, GOST 8777) and laboratory equipment standards cited in the original text. It also replaced an earlier edition, GOST 10772‑64.

Q: Is it part of a series?

A: It is part of the family of GOST standards addressing foundry materials, test methods and industrial safety. It references and relies on multiple other GOSTs for test apparatus and safety rules and is typically used together with related foundry and packing standards.
